,new and useful Improvements in Silding-Door Tracks and Hangers, of which the following isa specification.

This invention relates to sliding-door tracks and hangers; and its objects are, first, to produce a noiseless track and means for vertically adjusting the same; second, to provide means'for disconnecting a hanger from the top of a door without disturbing its ver-- tically-adjusting mechanism, and, third, to afiord means for vertically adjusting a hanger by lengthening or shortening it without disconnecting it from its door.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a sliding-door track and hangers embodying my improvements. Fig. 2 is an end view of the same. Fig. 3 is a detailed end view of one rail of the track and its supporting-trough. Fig. 4 is an isometri'oal'detail'of a fragment of the railsupporting troughs of the track, a screw for adj ustably connecting such troughs with their soflit, and a front door-stop. Fig. 5 is an isometric detail of devices for supporting unadjustably one end, as S, of the track. Fig.

6 is an isometric detail of two fragments of the connecting-webs'of the Tail-supporting troughs and aslightly-yielding joint connecting their adjacent ends together. Fig.7.is an isometrical detail of a complete, hanger minus its wheelsgthe wheel-frame being disconnected from the otherparts thereof. Fig. 8 is an isometric detail of the parts unassembled composing the hanger shown in Fig. 7- minus the wheel-frame. Fig. 9 is a detail of the parts of the hanger shown in Fig. 2. Like letters of reference indicate corresponding parts throughout the several views. 45

A represents parallel metal troughs connected by a supporting-web A and are preferably integral. 1

B represents preferably continuous rails of wood or fibrousunaterial resting in and supported by the troughs A and projecting above the edges thereof to prevent the hangerwheels from coming in contact therewith.

O is any suitable non-conducting or sounddeadening material, as felt or. the like, interposed in sheet form between the rails B and the inner surfaces of the'troughs A.

D is a soffit provided with downwardly-projecting lugs D, having threaded screw-holes extending vertically upward therethrough to receive screws, referred to hereinafter.

E, Figs. 1 and 6, is a semitoggle-joint connection between the adjacent but non-contiguous ends of the two pairs of troughs A, formed by means of a metal strap E, rigidly secured into the interior of one of. the supporting-websA of such troughs by means of rivets E extending therethrough and yield- F represents screws for suspending and ver-v I tically adjusting the completed track, Figs. 1 and 2. Each of these screws, Fig. 4., has formed thereon an annular shoulder F adapted to engage the retaining-lip F on the web A, which retaining-lip F and screw-head F insure vertical adjustment of the track by turning the screw F up-or down, as may be required. V

G is a door-stop secured to the bottom of the troughs A by means of screws G, provided with a rubber buffer G and rendered longitudinally adjustable by the longitudinal slots G3 therein.

H is a track-suspending loop secured to and depending from the under side of the soifit D.

H" is an L-shaped suspending-lug having its vertical arm H secured to the web A of the troughs A and its horizontal arm H inserted into the loop H.

I is a base-plate having horizontal slideways I' l thereon, the latter also having a longitudinal slot I in the top thereof to admit a part to be described hereinafter.

Slight. yielding of the semitoggle joint E, .operatingin conjunction with the flexibility of the rails B, renders the track, Fig.1, vertically adjustable. As indicated by the.dot-.
